Wow, did this book turn around.I started this book thinking it was going to be this cute story filled with some swoony boys. I was disappointed.The book really was nothing like that. The tone of the story is very young. VERY young. There are a plethora of exclamation points that stuck out like sore thumbs to me in the beginning, then towards the middle of the book, I realized that it actually fit the book perfectly. That's how teenagers act. Everything is so exciting! And if it's not exciting, it's the end of the world! It's important! And life changing! And, and, and!!! I had a lot of trouble connecting with Sadie through most of this book. I wanted to kick her in the forehead more than once. I thought she was frustrating and childish and immature. And then--hello, Bri!--I realized that, duh, she is. She's all those things because she's seventeen and she's in love with a boy who doesn't love her back and it's the end of her world.While I enjoyed this book and gave it four stars, I really think this is geared more toward actual young adults, and I think it will strike a chord with many a girl. In the end, the message this book sends is wonderful. It's so hard to find a YA book that speaks to its audience, and if it does, that it has a worthy and worthwhile message. This one so does. And when I think about it, the message is good for every girl or guy, of any age, that has given up a part of themselves for someone they liked...or loved.While I didn't jive with all of this book, when I finished it, I actually said, "Wow." It was a story where you could see growth--major growth. The MC figured things out, made changes--sometimes difficult changes--and she came out on the other side a better person.I only wish every YA novel managed to achieve that.
